Abstract:

The topic of this Master's thesis is the change of use of a storage building Makasiini located in Suvilahti, Helsinki. The building is part of the culturally significant industrial environment of Suvilahti. The building is not protected by the town plan, but by the Helsinki City Museum. Needs for conservation have been defined in cooperation with the Helsinki City Museum. Most important needs concern the buildings appearance and its spatial and structural qualities. The buildings historical values concern its original symmetrical form, its previous modifications, structures, materials and accessories. Buildings original spatial and structural values and characteristics must be identified and preserved.

History of the whole industrial area and its buildings is researched in order to understand its architectural value. Makasiini is researched more specifically. It is analysed by its facades, structures, materials, accessories and by its relation to other buildings in the area. This is done by researching written sources and archives and by visual examination of the building itself.

The main objective of the design is to preserve the old building. The most important thing considering this objective is to increase the use of the building. The building is at the moment in a rather weak condition. Nearly all new uses would require a renovation and some degree of improving its energy economy. In this thesis it is done by installing mechanical ventilation and by improving the energy economically weakest links which are its roof, base and windows.

The main architectural idea of the design is to make as little changes in the original building as possible. No parts will be reconstructed but all its previous modifications will remain unchanged. Also a new layer reflecting the cultural production of Suvilahti will be created. All changes are made so that the building can be restored to the state before these changes. In this design there is also presented an underground extension on the north side of Makasiini. By building the extension underground the relations between existing buildings remain unchanged.

The new use of the building is chosen by doing a usability research. In this thesis it is a brewpub. Main reasons for this are the objectives of increasing the amount of public buildings in Suvilahti and enabling the integration of the actors in Suvilahti. At the moment Suvilahti is quite closed. Although there are a lot of public outdoor areas there are little public buildings. All the public functions of the restaurant will be in Makasiini. The extension hosts auxiliary spaces that don't require natural light. Restaurants outdoor area is located in the upper garden and thereby increases its use. The gross floor area is 706,5 m2 (existing building 473 m2 + extension 233,5 m2).Diplomityön aiheena on Helsingin Suvilahdessa sijaitsevan varastorakennuksen, Makasiinin, käyttötarkoituksen muutos. Rakennus on osa Suvilahden rakennushistoriallisesti merkittävää kulttuurihistoriallista ymparistOa. Rakennusta ei ole suojeltu asemakaavalla, vaan suojelusta vastaa Helsingin kaupunginmuseo. Tässä työssä Makasiinin suojelutarpeet on määritelty yhteistyössä Helsingin kaupunginmuseon kanssa. Tärkeimmät suojeluperiaatteet liittyvät rakennuksen ulkoasuun sekä sen tilallisiin ja rakenteellisiin ominaisuuksiin. Makasiinin historialliset arvot liittyvät sen alkuperäiseen symmetriseen muotoon ja ulkoasuun, muutosvaiheisiin, rakenteisiin ja pintakerroksiin sekä kiinteisiin rakennusosiin. Rakennuksen alkuperäiset tilalliset ja rakenteelliset arvot ja ominaispiirteet osana Suvilahden teollisuusalueen historiallisesti arvokasta kokonaisuutta on tunnistettava ja säilytettävä.
